JOHN M. eoonwm', OF-"MOUNT VERNON, NEW YORK.

.DUIVIIPING-VEHICLE.

citizen of the United States, and .a resident of the city of MountVernon, in the county of Westchester and State of New York, haveinvented certain new and useful Improvements in Dumping-Vehicles, ofwhich the following, taken in conjunction with the accompanymg drawings,is a full, true, and concise specification.

My invention relates to improvements in dumping-vehicles, and moreparticularly to certain lmprovements in the structural formation of, theinclined bottoms of the cargo- ""and more appended c aims. I 2

the invention.

1 parts broken away and insection. Fi

I shown in Fig. 2, wherein it W1 carr in rece tacles thereof the ob'ectof y g r 1 my lnvention eing primarily to increase the durability andload-carrying powers of .such

vehicles at a minimum of cost and without sacrifice to lightness ofweight and load-resisting 'owers.

To t is end the invention comprises-the various features hereinbelowfully described rticularly pointed out in the he drawings exhibita'preferred form of Figure 1 is a top plan of a vehicle with 2 is avertical section taken on line 2 2 of 1.

Fig; 3 is an enlarged sectional detail showing the'gusset-sheet andcognate parts;

Fig 4, a sectional view on lines 4 4 of Fig. 3. ig. 5 is a detail inside elevation of a portion of 'theexterior of the vehicle. Fi 6 is adeveloped blank from which the oor-sections are formed. Fig. 7 is a"developed blank from which the center valve-sections are formed; andFig. 8 is a detached view of a center valve-section, showin theantifriction-roller.

Referring first to igs. 1 to'5, the cargoreceptacle of the vehicle isformed ,by two end bulkheads 1 1 of any appropriate construction andtwo. parallel. and upright side walls 2 2. The side walls are shownherein as formed each of a continuous sheet of metal connected by itsends with the end bulkheads and having a lateral top flange'2. 1 Thebottom of the rece tacle' is formed by two fixed outer-floors am twocenter ivoted floors'or valves presently to be descrl ed, and thearrangement of these floors is referably as 'lFbe seen that thebottom ofthe rece tacle pitches inwardly from both sides. T e fixed or upperinclined floor, which extends the entire length is formed of apluralitof flanged sheet-metal sections 3, allof simi arshape and arranged sideby'side, so that their'flanges occupy planes which are transverse to theaxis of the vehicle, while their outboard ends are adjacent to the lowermargins of the side walls 2, to which they are securely fastened. Thediagram of. Fig. 6 indicates the manner of formin these floor-sectionsfrom a flat sheet. A blank is first cut of the sha e shown in this fiure, and

the sides are bent ownat right angles to the body to form the sideflanges 44. The marins of the flanges thus formed are then bent inwardlyto form stiffenin -rims 5 5, and the inner separated ends' of 't eflanges 4 4 are bent in at right angles thereto to form the tabs 6. Theside flanges are of less length than the body portions, 'so that thereis an overhang at each end. The outboard overhang 3'? is bent upwardlyat an obtuse angle, as shown in Fig. 3, while the inboard overhang isallowed toremain flat. When the sections are in place, the overhang orupwardly-bent flange 3 is'fastene'd to the face oi the side wall,asshown in the drawings, and the edge of the'flan es 4 4 or the rims 5 5rest .upon theinward y-turned bottom flange 2 thereof, so that thestrainof the. load at the outer ends of the floor-sections is transmitted tothe sides at two separate points. If desired,

a further reinforcement may be provided by inserting an obliqueangle-iron? in the an le between the flanges 4 4 and theside wal 2.' Thefloor-sections are united together by their side flanges and are furthersupported from the sides of the vehicle b means of thetriangulargusset-sheets 8, whic have their lower extremities interposedand secured between the proximate flanges 4 4, Fig. 4, while their outermargins are connected to the face of the side walls by means of the twoangle-irons 9, Figs. 1, 2, and 3, the

latter being riveted through the side walls to the verticalstiffener-beams 10 on the exterior thereof. .The bases or lowerextremities of the gusset-sheets 8 are substantially equal in width tothe length of the side flanges 4 of the floor-sections, so that theytherefore support the floor throughout its entire width and at a (pointbelow its upper surface. The inboar supported by a longitudinal beam orbar 11, which finds its support upon the end bulkheads by means ofsuitable brackets'12, planted thereon, as shown in Figs. 2, 3, and 4.

, f th receptacle and on each side of the same This bar is preferably aZ-beam, having its ends of the several floor-sections are IIO ' when inclosed position have their free cape over one or both of the F. .Eth

a and of a character to up er flange turned toward the center of the veiicle and adapted to form the support for the flat (Werhanging ends ofthe floor-sections, while its other flange is disposed beneath theflanges 4 and rims 5, to which it is secured. The web of the Z-beam isalso sooured to the flanges 4 4 by being riveted to the tabs 6.

The two 2 beams 11 mark the lateral boundaries of the centraldischarge-opening of the vehicle, extending from bulkhead, to bulkhead,through which the cargo is adapted to ass when released, The centerdumping vali es 13, which constitute the movable floors of the bottom ofthe rece tacle, are adapted to close this opening, as slicwn in F .2,and edges directly beneath the inwardly-turned flanges of the Z-beams.of a number of sheet-metal sections each cut "from a flat blank withtriangular ends or end flanges 14, Fig. 7, which ends are subsequentlybent down at right angles, as shown in Fig. 8, the margins of the flatbo dy portion, as well as of the end flanges, being turned at rightangles to provide the stiffening-rims 13. The several sections areplaced end to end and joined together by their proximate end flanges,and the apices of the united flanges are spread apart and perforated toreceive and support an antifriction roller 15. The two center valvesthus formed are pivotally sup orted by means of hinges 16 u on thecentra longitudinal shaft 17, carrie( by the pedestals P, and they areheld in closed position by the rollers 15, resting upon the rotarydetents C C on the rock-shafts O C. When one or both of these shafts areslightly turned, the valve or valves fall, opening the'discharge-orificeof the receptacle and permitting the cargo to esdischarge-chutes Byturning up the pivoted chute-section e cargo may be discharged directlybeneath the car.

It will be seen from the fore oing that the floor-sections formed asdescri ed and combined with the gusset-sheets form a rigid inclinedfloor or hopper-bottom for the receptacle, which is not likely to becomedistorted, and that therefore the margins of the discharge-opening willat all times be straight cooperate properly with the valves.
